Vince introduces the new E&C "EBS" (Electronic Blowback System) airsoft rifles that is available at his very own Vincent’s Hobby Shop. He features several models, including the EC 603 MK18 and the EC 633 SOP MOD, which features a stylish two-tone platinum finish. It’s clear that these rifles are designed for players who want the mechanical feel of a gas blowback rifle without the hassle of constantly refilling green gas.
